Programs to open CMG file

Remember to download programs supporting CMG files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of ChessMaster with CMG files

If the application is or has been freshly installed, but the CMG file still does not use the ChessMaster program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the CMG file with the ChessMaster application.

Step 3. Update ChessMaster to the latest version

The fault may also lie with the ChessMaster program, it is possible that ChessMaster Saved Game requires a newer version of the program. In this case, use the Ubisoft Entertainment S.A. website or update the program from the application.

Step 4. Check for the following problems with the CMG file

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. Usually this applies to CMG files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file CMG or the program directory. However, remember that not every infected CMG file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the CMG files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular CMG file corruption. The easiest way to restore the file is from a backup or by contacting Ubisoft Entertainment S.A., but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted CMG files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the CMG file to another location.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes you have to wait for the session to the file CMG to close. However, some background programs may block the CMG file while scanning. If the problem persists, restart the machine.
